Abstract
Description
- The present invention relates to reclosable packaging such as plastic bags and, in particular to a tamper evident package and a method of manufacturing such packages on form, fill and seal equipment so as to render the package tamper evident to an ultimate consumer.
- Reclosable bags have become increasingly popular both for storage purposes and as primary packaging for foodstuffs and other commodities. The closures for such packaging consist of a pair of profiles having mating interlocking elements and may have webs to facilitate joining the zipper to the package material. A slider may be provided to facilitate opening and closing the zipper. Where the package is to be used to contain food stuffs, it is important to provide the package tamper evident. That is, the consumer should be able to quickly determine, by simple inspection, whether the package has been previously opened since the time it was filled. A common way to provide such tamper evidence is to provide a header of some form extending over the zipper which must be removed before the consumer has access to the zipper. Once the header is removed, the package may be opened and reclosed with the zipper but the removed header provides clear evidence of the initial opening of the package.
- When the zipper on such packaging is provided with a slider, it is difficult to provide a header going over the slider without introducing wrinkles or puckers in the package film forming the header. Not only do such wrinkles and puckers waste film, but they also render the packaging untidy.
- The above problems of the prior art are effectively resolved in accordance with the present invention by providing an improved tamper evident package that may readily be modified to accommodate a zipper slider without detracting from the appearance of the package or its ability to provide tamper evidence. The improved reclosable package has a first wall and a second wall facing the first wall. A zipper is provided at a top of the package. The zipper has a first profile attached to the first wall and a second profile attached to the second wall. The first and second profiles respectively have mating first and second interlocking members. The first and second walls include portions that extend over the zipper and the first wall extension portion has a line of weakness that extends parallel to the zipper. The line of weakness may be a line of perforations or a score line extending partially through the package film. A peel seal joins the first wall and the second wall above the interlocking members of the profiles and sections of the first and second walls extend beyond the peel seal. If the zipper has a slider, a pocket is formed in one of the walls to accommodate the slider. The pocket extends parallel to the zipper.
- A consumer first opens the package by separating the top peel seal and pulling the wall extensions apart. This action serves to rupture the line of weakness exposing the zipper and providing permanent evidence that the packaging has been opened. The consumer may then rely on the zipper to open and reclose the package as required.
- The present invention is shown in the accompanying drawings wherein:
-
FIG. 1 is a simplified side sectional view of a tamper evident package in accordance with the present invention; -
FIG. 2 is a view similar toFIG. 1 showing a modification of the tamper evident package; -
FIG. 3 is a front view of a package in accordance with the present invention, for simplicity, one wall of the package is removed so that the components of the package may be better seen; -
FIG. 4 is a diagrammatic view of a first method for forming a package in accordance the present invention on vertical form, fill and seal (VFFS) equipment; -
FIG. 5 is a diagrammatic view of a second method for forming a package in accordance the present invention on horizontal form, fill and seal (HFFS) equipment; and -
FIG. 6 is a diagrammatic view of a third method for forming a package in accordance the present invention on HFFS equipment. - Reference is now made to the drawings and to
FIGS. 1 and 3 in particular wherein apackage 10 in accordance with the present invention is depicted comprising afirst wall 12 andsecond wall 14 respectively forming the front and back of the package. Azipper 16 is provided at the package top. Thezipper 16 includes first andsecond profiles mating interlocking members flanges flanges walls seals peel seal 36 may be provided joining the interior surfaces of thewalls flanges flanges peel seal 34. The walls of the package includeextensions peel seal 42 withportions peel seal 42. - The
package front wall 12 is formed with a line ofweakness 48 inextension 40 aboveseal 32 and preferably below the interlockingmember 24 ofprofile 20. The line ofweakness 48 may comprise a line of perforations or a score line extending partially through the film ofwall 12. The package is completed byside seals bottom seal 54, if required. If the package front and rear walls are formed of a single, folded sheet, the bottom seal may be replaced by a fold line. Thepackage 10 further includes athermoformed pocket 56 to contain aproduct 58. - The
package 10 a depicted inFIG. 2 is substantially the same aspackage 10 except that theextension 40 a comprises a separate strip of film joined by aseal line 60 to the exterior ofwall 12. Thestrip 40 a may conveniently be printed to form a label for the package. - In both cases the
zipper 16 is provided with aslider 62 which rides on themating interlocking members wall 14 is provided with apocket 64 that extends parallel to the zipper in line with the slider so that theslider 62 seats in thepocket 64. - In use, the consumer grips the
top portions peel seal 42 to open and the line ofweakness 48 to rupture thereby exposingslider 62. The user may then useslider 62 to open and reclose thezipper 16 to gain access to the package contents. - Reference is now made to
FIGS. 4, 5 and 6 wherein representative methods of forming thepackage 10 are depicted. InFIG. 4 a vertical form, fill andseal machine 70 is depicted. Apackaging film 72 is fed fromsupply roll 74 past adevice 76 for forming a line ofweakness 78 adjacent but not at aside edge 78 of the film. Thedevice 76 may comprise a serrated wheel for forming a line of perforations. Alternatively, thedevice 76 could be a laser or other means for scoring thefilm 72 to form the line of weakness. Apocket forming mechanism 80 is provided at the side offilm 72 opposite to thedevice 76. The pocket forming mechanism could be a vacuum forming die if thefilm 72 lends itself to vacuum thermoforming. Alternative a plow mechanism could be used to deform the film under the plow into a pocket. In either case, a series ofpockets 82 are formed in thefilm 72 spaced at bag width intervals. The film 72 (now having the line ofweakness 78 and pocket 82) is then fed over collar 84 that folds the film about fillingtube 86 by bringing the longitudinal edges of the film together in a fin. Azipper 88 with attachedsliders 90 is fed fromsupply 92 into the fin and attached within the fin by sealingbars 94. The sealing bars also serve to activate appropriate coatings on the film (if necessary) to form the peel seals 42, 34 or 36. Longitudinally extending bands of peel seal material may be provided on thepackaging film 72 and/orzipper 88 to facilitate forming the peel seals 34 and/or 36 and 42 simultaneously with the attachment of the zipper to the packaging film. The package is then completed by forming transverse seals with sealingbars 96 after being filled throughtube 86. - In
FIG. 5 a horizontal form, fill and sealmachine 100 is depicted for forming a package from a single sheet of film. Apackaging film 102 is fed from asupply 104 past adevice 106 for forming a line ofweakness 108 adjacent but not at aside edge 110 of the film. Thedevice 106 and the line ofweakness 108 may be as described above. Apocket forming mechanism 112, as described above, is provided at the opposite side of the film to form a series of slider pockets 114. After aproduct 116 is fed onto the film fromhopper 118, the film is folded over the product bringing the edges substantially together. Azipper 120 with attached slider is fed between the film edges and positioned with a slider in each formed pocket. The zipper is attached byseal bars 122 which also form the package peel seals, as also described above. The package is completed with cross seals formed by seal bars 124. - In
FIG. 6 a horizontal form, fill and sealmachine 126 is depicted for forming a package from a double sheet of film. Thebottom film 128 may conveniently be a thermoform film fed from asupply 130 past heated dies 132 and 134 with which aslider pocket 136 and aproduct pocket 138 are formed. aproduct 140 is then fed into eachproduct pocket 138 throughhopper 142. The bottom film is then fed past azipper applicator 144 which applies a length ofzipper 146 with an attached slider transversely to the bottom film so that the zipper slider is positioned in the slider pocket. Atop film 148 is then fed fromspool 150 over the bottom film. The top film may be preformed with lines of weakness of the lines of weakness may be formed bydevice 152 as the top film is fed over the bottom film. In either case, after the top film is positioned over the bottom film, side seals 50, 52 are formed byseal bars 154 and the zipper is attached to the top film byseal bars 156 which also form the package peel seals, as also described above and thepackage bottom seal 54. While the zipper applicator in this embodiment is shown applying thezipper 146 transverse to the running direction of the films, it should be appreciated that the zipper could readily be applied in the machine direction in the manner described in connection withFIG. 5 . That is, the zipper (with attached slider if desired) could be fed ontobottom film 128 before the top film is fed over the bottom film and then sealed to the top and bottom films. The slider pocket would then also be formed as described above in connection withFIG. 5 . - Thus, in accordance with the above, the described packages may be effectively formed.
